Concrete Flooring
There are many types of concrete available, created by varying the proportions of the main ingredients such as Portland cement, aggregate mixtures (chemical and mineral additives) and water. In this way the finished product can be tailored to its application with varying strength, density or chemical and thermal resistance properties, with aesthetically pleasing consequences.
Concrete is strong in compression, as the aggregate efficiently carries the compression load. However, it is weak in tension as the cement holding the aggregate in place can crack, allowing the structure to fail. Reinforced concrete solves these problems by adding steel reinforcing bars, steel fibres, glass fibre or plastic fibre which then allows the concrete to withstand the tensile loads upon it.
McM has, over the years, completed many new concrete flooring projects and concrete floor repairs for a wide variety of customers throughout the Western Cape using the above techniques. MCM concrete flooring projects have included:
Spalling Repairs – Premature concrete surface failure is referred to as spalling and occurs when the water in the concrete goes through, so-called, freeze-thaw cycles. This can occur when a contractor adds too much water, under-finishes or over-finishes the surface resulting in a surface that is susceptible to contraction and expansion. The failure generally appears after a particularly cold or wet winter and as the degraded surface becomes unsafe, repairs need to be effected. The process usually included cutting out the spalled area, preparing steel rebar, coating the rebar, and reinstating the concrete with a more acceptable mixture.
Cracked concrete surfaces and other repairs
Coating of floors, using high build epoxies, polyurethanes and screeds
Waterproofing of concrete roofs (torch-on applications, etc.)
